Error Uploading App Clip to App Store Connect from Xcode

I am trying to build an App Clip and upload it to the App Store!
I am running Xcode 12 GM Seed from an external drive.

When I Archive it, select App Store Connect, and sign it, it says App Store Connect Operation Error - Could not find or load main class

Please help!

Might want to run it from your boot drive, instead.
